Blood counts can be normal in patients with pneumonia, and abnormal blood counts are not necessary for the diagnosis of pneumonia. In addition, in the case of infection by special pathogens, special groups of people, and after taking medication, the blood routine is often normal.
1. Infection of special pathogens: Pneumonia caused by bacterial infection is more common, but in fact, the clinical situation can often see pneumonia caused by viruses, mycoplasma, chlamydia and other infections, at this time, the blood routine can be no obvious abnormality.
2. Special groups: such as the elderly body resistance is poor or immunosuppressed patients (such as tumor chemotherapy or long-term application of prednisone and other glucocorticoid therapy patients), white blood cell values may be relatively low.
3. Patients who have taken their own medication (e.g. cephalosporins, levofloxacin and other antibiotics) and then go to the hospital for review, the white blood cells may also be normal.
Bacterial pneumonia is the most common type of pneumonia, most of the blood tests will suggest that the white blood cells are abnormally high or low, and sometimes due to differences in the pathogens of infection, the patient’s immune status and other blood tests will remain within the normal range, it is recommended that the patient go to the hospital in a timely manner to conduct the relevant examinations, to clarify the diagnosis and then give the appropriate treatment.
